The seat 23`tapers upwardly iorvvardlytoV 'form an inclined wall to receive the tip'of the bar, andi the' end of tli'ebalrl'is tapered! ripeV wardly outwardly from the tip. N

rlhe floors of the recesses 22 are` substa'nlv tially perpendicular to the axis oitlie hOOsk to form horizontal seats fnrthe'lii'gsll, and;

the iront walls 27 of the recesses incline up wardly 'forwardlyto the-.stop wallV ri'flie spring 2e bears against the arcuate end of the latchingbar rearwardly of the' aXis Athereofand rearwardly of the upper end of the slot therein but adjacent the end ofthe slot.

rThe pin 16 is mounted a substantial distance in iront of the axis of thel hook and substantially in alignment with the seat of the bill, whereby the lower end of the bar tends to move forwardly from the recess to the bill.

In order tor assemble the bar 17 in the hook the upper face of the wing is provided with a rectangular' opening 28 having side grooves 29 to receivethe lugs 2lV so, that'the bar can be inserted therethrough into the channel l2. The lugs 2l enter the grooves 2O through an opening 3() i'ormedil sockets 22. Y v

In using the device, 'the' operator may eX'- tend his fingers through the opening and press the bar intothe body recessior admit'.

ting a bail to the hook. V-henthe bar` isV re-l v leased it pivotson the pin, the lower end mov-v ingtoward the bill, andthe springQe'ltendsto shiit the bar longitudinally andi' assure theY entrance of the lip into the recesses`22.

The bar thus latches a bail in the hook, `and cannot be accidentally*displaced should' the bail or' elevator supported therebybe jarred or catch on derriclr structure. rlhe bar is protected from accidental disturbance and has no projecting parts except the lower end which is securely retained by the rear walls of the recesses.

The bar may easily belifted to dise'ngage` the lugsfromthe recesses, and pivoted rearwardly to open the entrance'tothe hook for `removing the elevator bail;
